architect

architect is a skill for Claude Code, Codex from robium-ai/robium. It costs 193 tokens per session (2,406 once invoked), scanned A, original, MIT.

An entry-point skill for planning new robotics applications. Robotics applications combine software with robots, sensors, simulations, physical environments, or visualisation tools.

In plain words
What is it for?
Use it when starting a robotics project, choosing a simulator or model, selecting hardware and compute, planning data or visualisation, or making a genuine architectural change.
Why use it?
It helps turn a rough idea into a small buildable first version while exposing important choices and risks. It also records architecture decisions and directs implementation to the appropriate specialised skills.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

architect scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.

architect

The entry point for a new Robium application. It combines a lean design conversation with robotics stack selection, chooses the cheapest meaningful proof, records decisions without freezing provisional assumptions, and routes implementation to the skills that own each layer.

When to use this skill

  • Starting a new robotics application from a rough idea.
  • Choosing or reconsidering the stack, simulator, embodiment, environment, data path, visualization, or compute target.
  • Decomposing a multi-subsystem robotics idea into a first buildable slice.
  • Writing a durable decision record for a new app or genuine re-architecture.
  • Skip architect for a bounded change in an existing flow. Read the affected code and use the matching tool skill directly.

Key directives

  • Delegation posture: route + embed decision logic. Architect owns the product/stack choices and routing. Tool mechanics stay in the skill that owns them.
  • Brainstorm only where a real decision exists. Inspect the repository and robium-apps registry first. Ask only questions whose answers materially change the first slice. For a genuine choice, offer 2–3 approaches with trade-offs and recommend one. Never announce a process classification.
  • One direction gate, then build. A new app or material architecture gets one rough direction approval. After that, proceed through implementation and verification; pause only for a material pivot, scope expansion, paid or publishing action, deployment, or safety concern.
  • Prove the riskiest assumption cheaply. Before polishing infrastructure or scaling compute, run the smallest probe that can disprove the stack and deliver the first user-visible working slice. Label provisional choices and update them when evidence changes.
  • Use a decision record, not a contract. Create or update docs/architecture-brief.md for a new application or genuine re-architecture. It records validated decisions, provisional assumptions, risks, and authorized pivots. Bounded feature/fix work does not require a new brief or approval cycle.
  • Environment first, syntax verified. Route reproducibility to environments before substantial code. Verify volatile versions, commands, and platform constraints against current primary sources or installed CLI help; never rely on memory.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

architect is a skill published in the GitHub repository robium-ai/robium (9 stars, last pushed 7d ago), licensed MIT. It adds 193 tokens to every session and 2,406 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
